Comparison of the air-sea flux algorithm for the evaporation duct diagnosis

Combing for the domestic and international diagnosis model of evaporation duct, the discrepancy of the parameter scheme of the flux algorithm in marine surface boundary layer is analyzed. The six parameter schemes of two roughness length functions (Fairall (2003), Liu (1979)) and three universal functions (LKB, RSHMU, Coare3.0) are compared using sea trial data. Show as a result: The accuracy of model decreases in shore with the increase of the stability, and is lower than open sea area. Under the different environment of sea area, the optimization combination (Fairall(2003) & Coare3.0) is confirmed.
